24 Claims.

The present invention relates to lubricators, and more particularly to a lubricator of that type adapted to be mounted against a rail for supply ing lubricant along one side of the head of the i rail so that the lubricant may be picked up by wheel flanges and distributed for a considerable distance along the side of the rail from the lubricator.

An object of the present invention is to provide is 1 an improved and simplified construction of lubricator wherein the lubricant is fed directly from a distributing pipe through suitably spaced nozzles carried thereby into the desired spaced apart positions along the side of the rail head, and to 35 I provide a protecting plate or means for preventing damage to the nozzles by the flanges of wheels passing over the rail.

Another object of the present invention is to provide a construction wherein the parts are so 20. mounted that the device may be adjusted and properly applied to rails worn to various degrees and to provide a lubricator comprising but relatively few parts which may be quickly interchanged upon wear or breakage of the parts, and

25' wherein the lubricator as a whole will accomplish the purpose by a relatively short flat structure which lies close against the rail and occupies but small space.

Another feature of the present invention is to i provide a lubricator with a distributing pipe so constructed and mounted that the pipe may serve as a bearing upon which the pipe may be rocked to dispose the nozzles of the pipe in the desired proximity to the rail head, and to provide means :17,- for facilitating the cleaning out of the pipe and nozzles.

With the foregoing and other objects in View, the invention will be more fully described hereinafter, and will be more particularly pointed out 451 in the claims appended hereto.

Figure l is a transverse section through the same taken on the line 4-4 of Figure 1 and showing the passages through the distributing 55 pipe and an adjacent nozzle.

Figure 5 is a transverse section taken through the lubricator applied to a rail on the line 55 of Figure 1 and showing the position of the protector plate over the feeding nozzles.

Figure 6 is a detail perspective view looking 5 at the inner side of the protector plate.

Figure '7 is a top plan view of the bracket employed for attachment to the rail web, and

Figure 8 is a fragmentary perspective view of oneend of the bracket, showing the vertical slots 10 for adjustment and the supporting blocks for the protector plate and distributing pipe clamps.

Referring to the drawings a conventional type of rail is shown having a base I5, a web I6 and a head I! at the top of the web which overhangs the opposite sides of the base IS.

The lubricator has a bracket plate I8 which is of less height than the web l6 and which is of desired lengths and provided at suitable points, such as near its opposite ends, with vertically 2 elongated slots IQ through which engage clamping bolts 26 or the like for binding the bracket l8 against the rail web. The bracket plate [8 is supported from the base 15 of the rail by means of set screws 2i which are threaded downwardly through lugs 22 projecting from the opposite lower corners of the bracket I8 and which are adapted to be turned 'down for raising the plate when the clamping screws 2|] are released. The bracket plate It is thus securely bound against the rail 30 .web in adjusted position and is securely supported from sagging by the set screws 2 I.

The inner face of the bracket [8 is relatively fiat, as shown in Figure 7, while the outer face thereof is provided at suitably spaced apart points with supporting blocks 23 which stand out from the plate to the desired extent and which are provided with upwardly and inwardly inclined outer faces, the outer faces of all of the blocks 23 lying substantially in a common inclined plane.

Each block 23 is provided with an outwardly extending threaded stud 24 adapted to receive thereon a clamping nut 25 for a purpose which will hereinafter appear. At each end of the bracket i8, and at its outer side, is an outstanding fiat rib 26 which preferably extends throughout the height of the bracket I8 and which is provided near its upper end with an outstanding threaded stud 2i upon which is secured one of the clamping nuts 25, the stud 21 being preferably in line with the studs 24.

Mounted on the bracket is a distributing pipe 28. The pipe 28 is of suitable diameter and of a length slightly broader than the bracket l8 and bears at its opposite ends and at its inner side against the lower portions of the ribs 26. The intermediate portion of the distributing pipe 28 lies beneath the blocks 23, and the pipe 28 is provided intermediate its ends with an attaching socket 23 or the like by means of which a source of lubricant under pressure may be connected.

The distributing pipe 28 is provided at opposite ends with removal plugs 33 by means of which the opposite ends of the pipe 28 maybe opened for the purpose of cleansing the pipe, and also.

to facilitate manufacture of the device. The pipe 28 is held to the bracket l8. by a pair of clamps 3| which are provided with socketed or strap portions at their lower end conforming to the size and curvature of the pipe 28 and which at their upper ends are provided with flat lug portions adapted to seat against the upper portions of the ribs 26.

These lugs of the clamps 3! are apertured to engage over the adjacent studs 21 and have their outer faces inclined to lie in the plane of the outer faces of the blocks 23. The clamps3l may be loosened sufliciently to turn the pipe 28 therein so as to turn the pipe to the desired degree for adjusting the distributor against the side of the rail. The clamps 3! not only hold the pipe 28 from turning when adjusted, but also rigidly support the distributing pipe on the bracket l8.

The distributing pipe is provided at its upper side with a desired number of distributing nozzles 32 which are in the form of small pipes securedito and communicating with the header pipe 23 and which extend upwardly therefrom and gradually merge into relatively flat broad outlet ends 33 which lie in a common plane lengthwise of the mainpipeor header 28. These nozzles 32. consecutively increase in internal cross sectional area toward the opposite ends of the header. or pipe 28 from the inlet flange 29 to equalize the feeding of the lubricant along the distributor throughout its length. The flattened upper ends of the nozzles 32. are adapted to lie against the side of the rail head IT, as clearly shown in Figures 3 and. i, so as to deposit at separate. spaced points along the rail head desired amounts of lubricant so that such lubricant will be inthe path of the flanges of wheels which pass. over the railto be carried by the flanges :and deposited along the rail head beyond the lubricator.

A protector plate 34 is disposed over the upper ends of the nozzles 32 for protecting the same against damage, particularly by contact with the flanges. of the wheels. Thisprotector plate hasa flat inner face, as shown in Figure 6, adapted to engage and rest upon the outer inclined faces of the blocks 23 and the lugs on the upper ends of the clamps 3|. From Figure 2 it will be noted that the nozzles 32 lie between the blocks 23 so that the nozzles are housed and protected not only between the blocks 23 but between the bracket plate 18 and the outer protecting plate 34. The nozzles therefore cannot be crushed by impact of objects brought against the side of the rail. The protector plate 34 is inclined upwardly and inwardly toward the head I? of the rail and is adapted to lie at its upper edge flat thereagainst. The protector plate is beveled at its outer side as at 35 and along its upper edge so as tolie closely against the side of the rail headl'l andtake up the thrust and wear of the wheelflanges, and the protector plate 34 is provided near its lower edge with vertically elongated slots 36 through which engage the threaded studs 24 and 21, the binding nuts 25 bearing against the outer side of the protector plate 34 for securing the same in vertically adjusted position.

The protector plate may be made of steel or any other hard material and its upper edge is preferably reinforced with some hardened substance, such as an alloy steel, toincrease the wear resistance quality of the protector plate.

The lower edge portion 31 of the protector plate 34 is relatively thick and uninterrupted throughout the length of the protector plate so as to give the necessary strength and rigidity thereto, and the protector plate is provided at suitable spaced apart points and in its inner side with recesses or depressions 38 which extend from a point in spaced relation to the lower edge of the protecting plate though the upper beveled edge thereof. These recesses 38 are disposed at points between the blocks 23 to receive and house the nozzles 32 for accommodating the nozzles and preventing any crushing pressure thereagainst. The upper ends of the recesses 38 terminate in openings or slots 39 in the upper inclined edge' portion of the protector. plate, and these openings 33 are of increasing lengths from the intermediate portion of the protector plate toward the ends thereof to snugly receive therein the upper outlet ends 33 of the nozzles, and the outlet ends 33are beveled in the plane. of the outer face of the protector plate so that lubricant ejected through the open ends 33 will be held against the side of the rail head and the upper edge portion of the protector plate and will not flow downwardly about the nozzles 32 and against the inner side of the protector plate. It will be noted from Figure 1 particularly, that the protector plate is provided with relatively long blank portions 40 between the nozzle openings 39, and these blank portions 43 are of sufficient extent to receive and 40 guide the wheel flanges over the openings 39 so that the wheel flanges will have no tendency to engage against the upper open ends of the nozzles 32. The blank portions 40 of the protecting plate thus provide a substantially smooth and uninter- 45 rupted guiding surface for the wheel flanges.

It will be noted particularly from Figures 1 and 2 that the upper open ends 33 which provide the discharge mouths for the nozzles 32;are of various port areas corresponding to the respective sizes of the nozzles 32' and increase successively. from the point of entrance 29 of the lubricant toward the opposite ends of the distributing pipe. It will also be observed from Figure 4 that these discharge ends or mouths 33 of the nozzleselie in close contact with the side of the rail headzl] so that the lubricant will be fed directly to the side of the rail head in the path of the wheel flange. The mouths or outlets 33 of the .nozzles are flat and elongated in the direction of the rail so as to provide a larger area over which the grease or lubricant is deposited on the rail head and wheel flange. The bracket I8 is vertically adjustable against the side of the rail and the distributing pipe 28 with its nozzles 32 is adjustable therewith so as to deposit'the lubricant at the proper elevation with respect to the rail head and wheelflange. The protector plate 34 is independently adjustable on the bracket .l8.so as to lit the protector plate about the mouths 33 7 of the nozzles when the latter are adjusted not only as to height but also as to inclination to insure that the nozzles are fully protected from contact with the wheel flange or otherobjects. brought against theside of .the rall.

When the device is applied as illustrated, grease or other lubricant is fed under pressure through the inlet 29 to the distributing pipe head 28. The lubricant under pressure passes toward the opposite ends of the header and is ejected upwardly through the nozzles 32, the nozzles of smaller cross sectional area receiving the lubricant adjacent the inlet pipe and retarding the too free ejection of the lubricant so that the pressure throughout the body of lubricant will be equalized in the outer nozzles 32 which are of increasing cross sectional area. In this manner and by this construction the lubricant will be ejected uniformly from all of the nozzles throughout the length of the device and the distribution of the lubricant will therefore be uniform and may be more readily controlled.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
